X-ray emission from Lyman emitting galaxies
Abstract
The early universe was reionized by Lyman radiation, but the Lyman escape fraction from most local galaxies is low. Two nearby Lyman-continuum-emitting galaxies are both luminous X-ray sources dominated by a single point-like source likely powered by accretion. Accreting compact object can produce powerful outflows that prevent scattering and allow Lyman radiation to escape. We propose to make the first X-ray observations of the third discovered nearby Lyman continuum emitting galaxy. Demonstration of a relation between strong X-ray emission and Lyman continuum emission would help understand how Lyman radiation escapes from galaxies.
